TEMPORARY BINDER.

SEGIFICATION forming part of Letters Patent No. 591,638, dated October12, 1897.

Application filed May13, 1897. Serial NoIA 636,279. (No model.)

To all whom t may concern:

Be 'it known that we, JOHN L. RILE and WVIL- LIAM J. RILE, citizens ofthe United States, and residents of Brooklyn, in the county of Kings andState of New York, have invented a certain new and useful Improvement inTemporary Binders, of which the following is a specification.

The invention relates to that classof binders sometimes known as rodbinders, in which a movable rod is employed to hold the pamphlets orsheets in place within the covers.

Ourimprovement consists in extending the rod loosely through lugs at thetop and bottom of the back, thus holding the rod always approximately inline with the back, but allowing suiiicient motion to permit the easyinsertion or removal of a pamphlet or sheet when desired. The lug at oneend, preferably the upper, is formed with a circular hole of a diametera little greater than the rod to allow the latter the required angularmotion without straining the lug or its fastening means. The opening inthe lug at the opposite end is peculiarly formed and locks theV rod instrong contact with the leaves or sheets when it is forced into oneportion of the opening, and when in another portion allows it to riseand relieve the pressure, but in both conditions the rod is held inengagement with both lugs and against displacement endwise.y

Another important feature consists in building up the inner face of thebackimmediately adjacent to the lugs, so that its surface lies at therequired short distance from the under face of the rod, or, ifpreferred, in contact therewith. These elevations serve to definite] ylocate the points at which the pressure upon the leaves is greatest, andone of them also performs, with the elasticity or spring of the rod,'theimportant function of holding the latter in the locked condition.

The accompanying drawings form a part of this specification andrepresent the manner in which we have carried out the invention.

Figure l is a face View of the binder with the covers open or extended.Fig. 2 is a corresponding section taken on the line 2 2 in Fig. l. Theremaining figures are on a larger scale. Fig. 3 is an end view of one ofthe ln gs, the inclosed rod being in vertical crosssection. Fig. et is asection corresponding to Fig. 3, taken on the line 4 4 in that iigure.Figs. 5 and 6 are sectional views similar to Fig. 4, but showingmodified constructions.

Similar letters of reference indicate like parts in all the figures.

A A are the covers, of the usual materials, ornamented and covered inany ordinary or approved manner, flexibly secured to the back B, andadapted to be folded upon each other to form a casing or portfolio forthe inclosed leaves or sheets. The back B consists of a strip of woodB,havin g the desired shape. lVe have shown it as semicircular incross-section, extending nearly the whole length of the covers andsecurely cemented to the flexible material b, joining them. To the inneriiat face of the strip are fastened the plates D and E, one at the upperandthe other at the lower end. Each is bent sharply upward at a rightangle, as shown, forming the lugs D E', through which extends thebinding-rod F. The upper lug D is provided with a plain circular .holed, receiving that end of the rod and allowing the latter suflicientliberty to turn freely therein and to be defiected angularly in alldirections to the extent required without tending to loosen the screws cc or otherwise straining the parts. A knob F', secured to the rod beyondthe lug D', prevents its withdrawal lengthwise. At the opposite end itpasses through the lug E, similar n all respects to the lug D',excepting in regard to the shape of the opening therein. The latter,instead of being, as before described, simply a circular hole, is apeculiarly-formed slot. .The main portion c is approximatelysemicircular, extending from a point near the upper end of the lug E tothe angle at the junction with the plate E and thence laterally at e ona slight` upward inclination, terminating in the circular pocketv e2,-about in line with the hole d in the other lug D. The pocket e2 isseparated from the semicircular portion e of the slot by thedownwardly-projecting tongue E2,the space between the point of thelatter and the bottom of c being just sufficient to allow the passagelaterally of the rod. A knob F2 at this end serves with the knob F toprevent the removal'of the rod, and also serves as a convenient meansfor grasping the end in transferring it from one portion of the slot tothe other.

IOD

G G- are pieces of thin wood or book-board fastened upon the upper facesof the plates D E. They are preferably beveled away from the adjacentlug, as shown, and are concealed by the strip of covering material H,neatly applied and cemented. The highest point on the face of the pieceG lies a little above the bottom of the slot e and a short distanceinward therefrom, slightly obstructing the free movement of the rod pastthe tongue E2 and requiring it to be sprung downward a little in passingto or from the pocket e2.

The elasticity of the rod allows this deflection and immediately springsback again so soon as the tongue E2 has been passed. Thus constructedthe movable end of the rod is held 3 lightly but reliably in eitherAportion of the slot.

The piece G with its companion lG at theIl opposite end also serve aspinching-surj faces upon which the leaves or sheets M are compressedbeneath the rod.

To introduce a sheet M, the knob F2 is-:de-

pressed and moved laterally until that'end of the rod is forced past thetongue E2 and springs upward in the portion e of the slot.

In this position one or more sheets oran open pamphlet to beheld betweenthe coversA-I` A may be easily slipped beneath the rod. The movable endof tlie latter is then forced i removal of thc sheets M or the receptionof others.

One of the main advantages of our in-venl tion is the constantengagement of the rod and holding it in such position relatively to theback and covers that t-he latter vmay be f opened and closed regardlessof the rod and .l without danger of loosening or breaking the in oneportion until it is forcibly transferred `to the other, all combined.and arranged to fastenings by careless handling when the ro is in theunlocked condition.

The lockingmeans is simple and effective and the whole is inexpensivetomanufacture 'l D', E carried by the back, a rod F extending and isneat and ornamental in appearance.

Modifications may be made in the .forms i and proportions withoutdeparting from `the principle of the invention or sacrificing kits jadvantages.

The vertical distance between the upper face of the piece G and thepoint of the tongue E2 may be varied, and will in some cases require tobe more or less than here shown to accommodate thick pamphlets or massesof sheets or to hold a single sheet reliably.

In the form shown in Fig. 5 the pieces G G are in one, extending thewhole length of the back'. In Fig. 6 these pieces are omitted,

the lugs and rod will be mounted on a stick erty to rise in the mainportion of said slot and be locked in said pocket portion, all combinedand arranged to serve substantially as herein specified.

2. In a binder, the back, the lugs secured thereto one -at each end, arod extending longitudinally of the back, held at one end in one of saidlugs, the opposite end extending -l through and held in a closedslot inthe other,

the said slot consisting of a main portionand a pocket portion, a tongueseparating said portions, the said rod being held in permanentengagement with both lugs with liberty, 'f -to rise .in the main portionof said slot and be lockedinsaid pocket portion, anda raised surface onVsaid back adjacent to said slot,

adapted to lock the said rod in said pocket portion by thespring of therod, all combined andarranged to serve substantiallyasherein specified.

3. The covers A, A and back B, the plates D and E fastened to the backand bent to form lugs D', E', a rod F extending longitudinally of saidback, held loosely in one of said lugs and permanently engaged in theother inthe closed slot comprising the curved portion e land pocket e2separated by the tongue E2., the latter serving to retain :the rod servesubstantially as herein specified.

4. The covers A, A and back B, the lugs longitudinally of the :saidback, held yloosely .in one of said lugs and permanently engaged IIO inthe closed slot e, e', c2 in the other, and the knobsF F2 on said rod incombination 4with theraisedsuzrface G on said back in such relation tosaid slot as to lock said rod therein by the spring of the latter, andthe raised surface Gvserving with said surface G and said rod to firmlygrip the sheets M at those points, allsubstantially as herein specified.

In testimony that we claim the invention above set forth We affix oursignatures Iin presence of two witnesses.
